Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell manufacturing, in particular to a stacked type power injection device. Background Art

[0002] Solar cells and photovoltaic modules will experience power attenuation after being exposed to light. Power attenuation will directly reduce the power generation of photovoltaic modules. When the power attenuation exceeds a certain range, the photovoltaic modules will experience large power generation fluctuations when the photovoltaic power station is in operation. In order to reduce the impact of this phenomenon, the photovoltaic industry currently adds anti-light decay equipment at the battery manufacturing end to treat the battery with anti-light decay, so that the battery function can be restored and reach a stable state. Research has found that the light-induced decay phenomenon of crystalline silicon solar cells is mainly caused by the BO complex in the silicon wafer, and hydrogen atoms have a good passivation effect on the BO complex. Therefore, injection equipment is currently often used to inject carriers into the battery cell to achieve hydrogen passivation, thereby reducing the impact of the light-induced decay phenomenon. Existing injection equipment mostly uses manual injection, which has a low degree of automation, low production efficiency and certain safety hazards. Utility Model Content
